the more open sections of the swampy thickets. A male that I shot I 

 have identified as the present race. The wing measured 78.3 mm., 

 and the bird is distinctly gray above. 



OPORORNIS TOLMIEI (Townsend) : MacGillivray's Warbler 



Sylvia Tolmiei Townsend, Narrative of a journey across the Rocky Mountains, 

 Apr. 1839, p. 343 (Fort Vancouver, Wash.). 



On October 31 1 shot an immature male near the ground in a weed- 

 grown thicket at 7,800 feet on Volcan de Agua, above Santa Maria 

 de Jesus, and on November 14 secured an immature female in a 

 weed-grown Held at Panajachel. 



CARDELLINA RUBRIFRONS (Giraud) : Red-faced Warbler 



Muscicapa ru'brifi'ons Gikaxjd, Description of sixteen new species of North Ameri- 

 can birds, 1841, (p. 27) , pi. 7, fig. 1 (Mexico) . 



On November 1 I collected two and saw others in a wooded valley 

 at 6,500 feet elevation on the north face of Volcan de Fuego, above 

 Dueilas. Another was secured among oaks at Chichivac above Tec- 

 pam, November 26. The birds move quickly through the trees feed- 

 ing in usual warbler fashion. 



In addition to these there are three other specimens from Guate- 

 mala in the National Museum. On careful comparison with a good 

 series from the mountains of southern Arizona, southern New Mex- 

 ico, and a few from northern Mexico I am not able to separate the 

 Guatemalan specimens as Griscom has done in describing Cardellina 

 ruhrifrons hella from Chichicastenango.^^ These warblers are sub- 

 ject to considerable wear and fading during the breeding season, 

 which lightens their color decidedly, many from the northern group 

 being summer birds in this condition. Griscom's specimens were 

 taken in winter, and those in the National Museum were obtained in 

 October and November. Lajdng aside the summer specimens in the 

 northern series and using only early spring or winter birds (from 

 northern Mexico), I am not able to detect any difference in shade of 

 red or gray or in the diffusion of reddish wash over the under sur- 

 face. It appears that all are the same. 



ERGATICUS VERSICOLOR (Salvin) 



Cardellina, versicolor Salvin, Proc. Zool. Soc. London, 1863, p. 188, pi. 24, fig. 1 

 (Chilasco, Baja Vera Paz, Guatemala). 



These beautiful warblers were fairly common over the mountains 

 from 8,600 feet at Chichivac to above Sierra Santa Elena. Eight 

 skins were taken at the latter point on November 18, 19, 20, 21, and
